Title: Ultrasonic range finder
Inventor: KOMACHI TAICHI
IPC: G01S15/10
Filed: 1986-05-09
Abstract: PURPOSE:To certainly measure the distance up to a reflecting article, by tracking the rising of the specific carrier ultrasonic wave contained in ultrasonic burst. CONSTITUTION:The ultrasonic wave from a transmitting ultrasonic transducer T is received by the distance calibrating ultrasonic transducer R0 provided at a position at a known distance L0. The output signal (r) thereof is converted to a rectangular wave signal (s) through an amplifying circuit a and a circuit RW for forming a reference wave into a rectangular wave and the phase difference between the signal (s) and the output signal of an oscillation circuit OSC is detected by a phase detector PHD. The output signal of the circuit PHD is converted to voltage by a phase/voltage converting circuit P/V to be held to a sample holding circuit S/H for a predetermined time, for example, only for a time divided at each burst rising point of time. The circuit OSC is constituted of a voltage control oscillation circuit and frequency changes so as to make the output (t) of the circuit PHD constant. The phase difference of ultrasonic waves is calibrated on the basis of the known distance L0 and the calibrated distance L is displayed on a display part DISP. Therefore, even when the collapse of the wave form of the rising part of ultrasonic burst is marked, an ultrasonic propagation time is measured and the distance up to a reflecting article is measured.

IPC: F24S50/20
Filed: 1983-06-15
Abstract: PURPOSE:To obtain the titled solar heat collector of a simple construction without using a motor or a complicate control mechanism by cuaisng the heat collecting surface of the heat collector to direct constantly in the direction of the sun in the duration of sunshine by a difference in the inner pressures due to the quantity of sunshine of a pressure vessel in which a low-boiling point fluid is sealed. CONSTITUTION:When the sun is at a position (A), the pressure vessel 12 receives sunshine on the substantially full surface, while on the other hand, a pressure vessel 13 does not almost recieve sunshine. Accordingly, the temperature of the pressure vessel 12 rises up, and its inner pressure also increases. It lifts a piston 6 within a pressure cylinder 4 to direct the heat collecting surface of the heat collector in the direction of the sun. Further, when the sun is at a position (B), the pressure vessel 13 receives sunshine to lift a piston 7 within a pressure cylinder thereby tracking the sun. Further, when the sun is at directly overhand, both pressure vessels receive the same quantity of sunshine, and hence the pressures of both pressure vessels are equal to eath other. Hence, the pressure cylinders 4 and 5 keep balance, and the heat collecting surface of the heat collector is directed right overhead.

Filed: 1990-04-25
Abstract: PURPOSE: To secure a favorable yield, by introducing and storing at least part of an oxygen-rich liquid component to and in a liquid air tank when the oxygen demand is large and again taking out the stored liquid component when the oxygen demand is small. CONSTITUTION: When the quantity of oxygen taken out of a conduit increases, an increased flow rate is set to an air compressor 1 and the flow rate introduced to a low-pressure stage 11 through an expansion turbine 7 is fixed. Therefore, the quantity of sucked air is introduced to a high-pressure stage 10 and increases the exchanging quantity of a fractionating tower. A liquid which increases correspondingly to the exchanging quantity is taken out through conduits 14 and 12 and an excessive liquid is stored in a nitrogen tank 35 and a liquid air tank 40. The increased liquid increases the introduction of the heat from a condenser/evaporator 48 and evaporated oxygen is discharged front a conduit 16. The liquid oxygen corresponding to the evaporated oxygen is taken out of an oxygen tank 32.  When a small quantity of oxygen is produced, the quantity of air introduced to the high-pressure stage 10 is reduced and the liquids in the nitrogen tank 35 and liquid air tank 40 are introduced to the low-pressure stage 11 and further introduced to the oxygen tank 32.
